I was 8 years old and I was alone in my parents' bedroom watching TV. My favorite channel was Cartoon network and "Courage the cowardly dog" was being broadcast at that moment.
My surprise was that, at that time, there was a new episode called 'Remembrance of Courage Past'.
I was not prepared for what I would experience. It's because that episode ended up being one of the saddest, and at the same time, greatest episodes I have ever seen in my life.
Until today I still cry whenever I watch it again.
